AMD announced the second-generation A-Series desktop APU lineup, based on the "Trinity" silicon. The silicon combines four x86-64 cores spread across two "Piledriver" micro-architecture modules, with a Radeon HD 7000 series graphics core with 384 VLIW4 stream processors, an integrated northbridge, and a dual-channel DDR3-1866 MHz integrated memory controller. Various models are carved out in the series by handling the numbers of CPU cores and stream processors. The company kicked off the lineup with two A10-5000 series quad-core models, which are fully-loaded with all components enabled. These are followed by two A8-5000 series models, which have four x86-64 cores, but just 256 stream processors for the GPU component. Just behind is the A6-5000 series dual-core APUs with 192 stream processors. Trailing the pack is the A4-5000 series dual-core APUs with 128 stream processors. Model numbers and specifications are tabled below. Prices range between $70 - $140.
